IBM operating systems have paralleled hardware development. On early systems, operating systems represented a relatively modest level of investment, and were essentially viewed as an adjunct to the hardware. By the time of the System/360, however, operating systems had assumed a much larger role, in terms of cost, complexity, importance, and risk.
IBM mainframes run operating systems supplied by IBM and by third parties. The operating systems on early IBM mainframes have seldom been very innovative, except for TSS/360 and the virtual machine systems beginning with CP-67. But the company's well-known reputation for preferring proven technology has generally given potential users the ...
An IBM System/360 in use at the University of Michigan c. 1969 IBM guidance computer hardware for the Saturn V Instrument Unit. On April 7, 1964, IBM launched the first computer system family, the IBM System/360. It spanned the complete range of commercial and scientific applications from large to small, allowing companies for the first time to ...
IBM enhanced one of GM-NAA I/O's successors, the SHARE Operating System, and provided it to customers under the name IBSYS. [1] [2] As software became more complex and important, the cost of supporting it on so many different designs became burdensome, and this was one of the factors which led IBM to develop System/360 and its operating systems ...
General Motors Operating System made for IBM 701 [2] MIT's Tape Director operating system made for UNIVAC 1103 [3] [4] 1956 GM-NAA I/O for IBM 704, based on General Motors Operating System; 1957 Atlas Supervisor (Manchester University) (Atlas computer project start) BESYS , for IBM 704, later IBM 7090 and IBM 7094; 1958
The GM-NAA I/O input/output system of General Motors and North American Aviation was the first operating system for the IBM 704 computer. [1] [2] It was created in 1956 by Robert L. Patrick of General Motors Research and Owen Mock of North American Aviation. [1] It was based on a system monitor created in 1955 by programmers of General Motors ...
OS/360, officially known as IBM System/360 Operating System, [1] [2] is a discontinued batch processing operating system developed by IBM for their then-new System/360 mainframe computer, announced in 1964; it was influenced by the earlier IBSYS/IBJOB and Input/Output Control System (IOCS) packages for the IBM 7090/7094 [citation needed] and even more so by the PR155 Operating System for the ...
Candle Corporation was an American software company active from 1976 to 2004. The company spent the first two decades developing system monitoring applications for a variety of IBM mainframes and their corresponding software, their first being OMEGAMON which saw quick widespread adoption in commercial enterprises.
